Expand description

List of arguments for a FunctionReference or a TermReference.

Function and Term reference may contain a list of positional and named arguments passed to them.

§Example

use fluent_syntax::parser;
use fluent_syntax::ast;

let ftl = r#"

key = { FUNC($var1, "literal", style: "long") }

"#;

let resource = parser::parse(ftl)
    .expect("Failed to parse an FTL resource.");
